The location at Dridu-Snagov, Ialomița County, Romania, situated in the Northern Temperate Zone, presents varying levels of suitability for solar PV energy generation throughout the year. This location experiences significant seasonal fluctuations in solar energy production, which is typical for regions at similar latitudes.

Seasonal Solar Energy Production

Summer stands out as the most productive season, with an impressive daily output of 6.66 kWh per kW of installed solar capacity. Spring follows as the second-best season, generating 5.07 kWh per day. Autumn sees a considerable drop in production, yielding 3.19 kWh daily, while winter experiences the lowest output at just 1.64 kWh per day.

These figures indicate that the location is most ideal for solar energy generation from late spring through early autumn. During this period, longer daylight hours and higher sun angles contribute to increased solar panel efficiency and energy production.

Optimal Panel Installation

To maximize year-round solar energy production at this location, fixed solar panels should be installed at a tilt angle of 38 degrees facing south. This angle is calculated to optimize the panels' exposure to sunlight throughout the year, taking into account the Earth's elliptical orbit and the location's latitude.

Environmental and Weather Factors

While Dridu-Snagov's location is generally favorable for solar energy production, there are some environmental and weather factors that could potentially impact solar panel efficiency:

1. Snow accumulation in winter: Heavy snowfall can cover panels, reducing their ability to capture sunlight.
2. Cloud cover: The region experiences cloudy days, particularly in autumn and winter, which can decrease solar energy production.

To mitigate these factors, consider implementing the following preventative measures:

• Install panels at a steeper angle to encourage snow sliding off
• Use anti-reflective coatings on panels to improve performance in low-light conditions
• Implement a regular cleaning schedule to remove snow and debris
• Consider using bifacial solar panels to capture reflected light on cloudy days

By addressing these potential challenges, solar energy production at Dridu-Snagov can be optimized, making the most of the location's solar potential throughout the year.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Dridu-Snagov

Seasonal solar PV output for Latitude: 44.7091, Longitude: 26.4503 (Dridu-Snagov, Romania), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:

 

Ideally tilt fixed solar panels 38° South in Dridu-Snagov, Romania

To maximize your solar PV system's energy output in Dridu-Snagov, Romania (Lat/Long 44.7091, 26.4503) throughout the year, you should tilt your panels at an angle of 38° South for fixed panel installations.

As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.

We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.

Seasonally adjusted solar panel tilt angles for Dridu-Snagov, Romania

If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Dridu-Snagov, Romania. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 38° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
29° South in Summer	48° South in Autumn	58° South in Winter	37° South in Spring

Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.

This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.

Calculate solar panel row spacing in Dridu-Snagov, Romania

We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Dridu-Snagov, Romania.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. Minimum Spacing:
   We add the shadow length to the horizontal space occupied by tilted panels.

This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.

Topography for solar PV around Dridu-Snagov, Romania

The landscape around Dridu-Snagov, Romania, is characterized by its gently rolling terrain and relatively flat topography. This area, located in the southern part of the country, is part of the expansive Romanian Plain, which stretches across much of southern Romania. The region is known for its fertile agricultural land, with vast open fields dominating the scenery. The terrain in this area is primarily composed of low-lying plains and small hills, with elevations generally ranging from 50 to 100 meters above sea level. The Ialomița River, a major tributary of the Danube, flows nearby, influencing the local geography and creating some subtle variations in the landscape. Scattered throughout the region are small forests and patches of vegetation, breaking up the otherwise open countryside.

Potential for Solar PV Development

The topography and land use patterns around Dridu-Snagov make it potentially suitable for large-scale solar photovoltaic (PV) installations. Several factors contribute to this suitability: Firstly, the predominantly flat terrain of the Romanian Plain provides ample space for the installation of solar panels without the need for extensive land modification. This flat landscape ensures that there are minimal obstructions to sunlight, maximizing the potential for solar energy capture throughout the day. Secondly, the agricultural nature of the region means that there are large, open areas that could potentially be repurposed or dual-purposed for solar energy production. These expansive fields offer the space required for large-scale solar farms without significant impact on densely populated areas or protected natural habitats. The areas most suited for large-scale solar PV installations would likely be the vast agricultural fields that are not prime farmland or are underutilized. These areas would provide the necessary space and sunlight exposure for efficient solar energy production. Additionally, locations near existing electrical infrastructure would be advantageous, as they would facilitate easier connection to the power grid. It's important to note that while the topography is favorable, other factors such as local regulations, environmental considerations, and grid capacity would need to be carefully evaluated before implementing any large-scale solar projects in the region. Nonetheless, the flat, open landscape around Dridu-Snagov presents a promising opportunity for solar energy development in Romania.
